Surgical treatment of chronic laryngeal stenosis secondary to vocal cord paralysis: pre and postoperative evaluation of ventilatory function.

Abstract
Thirteen patients with chronic laryngeal stenosis were operated upon with total excision of stenotic scar tissue, enlargement of the lumen by sectioning the back and front wall of the larynx, and application of an indwelling Teflon prosthesis for 4 months. The stenosis was in many cases caused by long-standing recurrent paralysis complicated by attempted surgical correction of the stenosis. Following operation, the specific airway conductance increased in all patients (mean +/- SD pre and postoperative values 0.51 +/- 0.30 and 1.12 +/- 0.51 kPa-1.s-1, respectively). The FIV1/FVC ratio was determined in 9 patients and an increase was postoperatively noted in all of them (mean +/- SD pre and postoperative values 43 +/- 17 and 76 +/- 13%, respectively). The physiological findings confirmed the excellent clinical results of the treatment.
